Electronic power module, and method for manufacturing said module

摘要

Said electronic power module (10) includes: a stack (14) comprising a metal layer forming an electric circuit (26) and intended for supporting an electronic power component (18) such as a semiconductor; a metal body forming a heat drain (20); and a dielectric material layer (22) forming an electric insulator and inserted between the electric circuit (26) and the heat drain (20). The stack (14) includes a composite material body (24) having a carbon-charged metal matrix. The carbon charge is between 20 and 60 volume percent. Said composite body (24) is inserted between an area of the electric circuit (26) and the electric insulator (22), said area being intended for supporting the electronic power component (18).
